9 - reg : specifies physical base address and size of the registers
10 - reg-names: should be "mac" for xHCI MAC and "ippc" for IP port control
11 - power-domains : a phandle to USB power domain node to control USB's
12	MTCMOS
13 - vusb33-supply : regulator of USB avdd3.3v
14
15 - clocks : a list of phandle + clock-specifier pairs, one for each
16	entry in clock-names
17 - clock-names : must contain
18	"sys_ck": controller clock used by normal mode,
19	the following ones are optional:
20	"ref_ck": reference clock used by low power mode etc,
21	"mcu_ck": mcu_bus clock for register access,
22	"dma_ck": dma_bus clock for data transfer by DMA,
23	"xhci_ck": controller clock
24
25 - phys : list of all the USB PHYs on this HCD
26 - phy-names: name specifier for the USB PHY
27
